The service lasted nearly an hour and included a video tribute to 13-year-old Beau and 16-year-old Calyx, who police say were shot to death by their mother last week.

The children's father, Army Col. Parker Schenecker, spoke during the service, thanking everyone for their support, said the family's spokeswoman, Lisa Eichhorn.

"Today is another day on our journey to healing," he said, according to Eichhorn. "While sadness seems to lurk right behind us every step of the way, I assure you that today's wonderful tribute to my children will keep me looking ahead. We would never have been able to get through this past week without family — and how lucky my children were to have such an incredible extended family."

The Schenecker family will continue to honor the memory of Calyx and Beau with a service 2:30 p.m. Tuesday at Christ Chapel Bible Church, 3740 Birchman Ave., Fort Worth, TX 76107.

The family asks that in lieu of flowers, memorials be directed to: the Calyx and Beau Schenecker Memorial Fund at the Community Foundation of Tampa Bay, 550 N Reo St., Suite 301, Tampa, FL 33609 or (813) 282-1975.
